Runs a deep mailbox existence check on every address and verifies catch-all, accept-all, and even SEG protected emails (Proofpoint, Mimecast, Barracuda). Keeps bounce rates under 5%, and the 30% of every B2B list that other tools flag as risky becomes deliverable again. The only catch-all email validation verifier that provides generous free trial.
